Our Executive Leadership Team

Bob Osbourne
Executive Director

Bob Osborne

A graduate of the University of Massachusetts, Bob’s career began in Africa with relief and development organizations including UNICEF and CARE. It was during his time in Kenya and Mozambique that Bob came to Christ through the influence of missionaries serving there. That not only changed the trajectory of his life but also his work.

Upon returning to the U.S., Bob served as Executive Director of the Charlottesville, Va., affiliate of Love INC and then as Director of Missions and Ministries at Trinity Presbyterian Church. Bringing together many aspects of his background, Bob joined Serge in 2002 as U.S. Director and was appointed Executive Director in 2005.

Bob and his wife Nancy have two grown children and in his spare time, he loves to garden and play bocce ball.

Senior Director of Mission

Josiah Bancroft

As a pastor, a church planter, and a missionary, Josiah has a heart to see God’s grace and power work in new ways in the church and throughout the world. A graduate of Covenant College and Reformed Theological Seminary, Josiah planted three churches in the U.S. before he and his wife Barbara joined Serge with their three children in 1992. Josiah was drawn to the work of Serge because of the organization’s commitment to grace and its focus on the gospel for the believer and through the believer to the world. Josiah served with Serge in a variety of roles until 2005, including team leader, pastor, field director, U.S. Director, and Missions Director. After co-pastoring Grace Community Church in Asheville, North Carolina for five years, Josiah returned to Serge in 2011 as Senior Director of Mission.

Josiah enjoys reading theology, poetry and novels, dabbling in tech, and Barbara’s marvelous cooking.

Senior Director of Operations

Matt Allison

Matt points to Serge as a ministry that has helped him know and experience the love of God since his childhood. While he was growing up, his mom and dad were impacted through the Sonship program and he experienced their life transformations in “real-time.” After graduating from Covenant College in Lookout Mountain, Ga., Matt joined Serge as part of the mission team in Bundibugyo, Uganda.

In Uganda Matt sought to share the love of the Father with the marginalized and poor, as a member of a larger Serge team focused on healthcare, education, evangelism, church strengthening, and other community development projects. Upon completing his term in Uganda, Matt returned to the U.S. and eventually pursued graduate studies at the University of Notre Dame and the University of Rochester.

In 2012 Matt returned to Serge to lead the mission’s mobilization effort. Matt and his wife Rachel live in West Philadelphia. He is a dedicated cyclist, including a regular 15-mile ride to work. His days are filled with travel, reading, hospitality, and membership at City Church, Philadelphia.

Senior Director of People Development

Lindsay Kimball

Lindsay was first introduced to Serge through a summer internship in Prague in 2008, followed by serving for two years with a church-planting team in Vienna, Austria. Her time on the field formed in her a passion to see missionaries renewed in the gospel in the midst of their labor, and to see missionaries cared for in ways that lead to longevity in ministry. Since 2012, Lindsay has worked in Serge's Home Office, first as a recruiter and Sonship mentor, followed by serving as Global Learning Leader, Associate Director of Mission, and most recently Member Care Director. Lindsay now serves as Senior Director of People Development, and loves thinking about and planning for how to help our workers and their families grow in resilience and thrive on the front lines. Lindsay earned her MA in counseling at Missio Seminary, and is a licensed professional counselor in the state of Pennsylvania. She lives in the Brewerytown neighborhood of Philadelphia, and enjoys biking, hosting friends, and serving with her local church community.
Deputy Director of Mission

Joel Hylton

A pediatrician by training, Joel fell in love with the vision of the Serge Ireland team during a short-term trip to help with the training of summer interns. He left his career in medicine in 2004 to join the work God was doing through Serge. In 2009, Joel and his wife Cindy moved to London to begin the Serge Apprenticeship Program there and has led the program as Area Director since 2012.

The father of four adult daughters, Joel reads, writes, hikes, and explores in and around London.

Our Founder

Dr. Jack Miller

Serge (formerly World Harvest Mission) was organized under the leadership of Dr. Jack Miller, a pastor, evangelist and author. In the late 1970s, the missions-outreach of the congregation he founded and pastored, New Life Presbyterian Church, was spreading beyond that local body.

Other church leaders gathered with Dr. Miller to work together in wider ministry. After many informal missions trips to Ireland and Uganda, Serge was officially established in 1983.

Today, Serge has over 300 missionaries serving in over 25 countries around the world.
